How often vs How many / How much ❌ How often books do you have? （错） ✅ How many books do you have? （对） 解析：How often 问频率（多久一次）；How many 问可数名词数量（多少个）；How much 问价格或不可数名词数量。 2. need to do 不要丢 to ❌ You need eat more vegetables. （错） ✅ You need to eat more vegetables. （对） 解析：need 后面接动词时要加 to，即 need to do sth.。 3. 频率副词不要放在 be 动词前面 ❌ I always am late. （错） ✅ I am always late. （对） 解析：频率副词要放在 be 动词之后，实义动词之前。 4. 三单主语动词要加 s/es ❌ She always do her homework. / He never exercise. （错） ✅ She always does her homework. / He never exercises. （对） 解析：主语是 she / he 时，do 变 does，exercise 变 exercises。 5. every day vs everyday ❌ I have breakfast everyday. （错） ✅ I have breakfast every day. （对） 解析：every day 是副词短语，放在句末作时间状语；everyday 是形容词，意思是「日常的」，如 everyday life（日常生活）。 6. once / twice 不要写成 one time / two times（口语除外） ❌ I play football one time a week. （错，书面语） ✅ I play football once a week. （对） 解析：一次用 once，两次用 twice，三次及以上才用 基数词 + times。 六、小拓展 1. 好习惯 vs 坏习惯 好习惯 Good habits 坏习惯 Bad habits get up early 早起 stay up late 熬夜 have breakfast every day 每天吃早饭 get up late and skip breakfast 起晚不吃早饭 eat more vegetables and fruit 多吃蔬果 eat too much junk food 吃太多垃圾食品 exercise every day 每天锻炼 never exercise 从不锻炼 do homework on time 按时做作业 do homework late 做作业拖到很晚 go to bed early 早睡 watch TV too long 看电视太久 help with housework 帮忙做家务 never help at home 在家什么都不做 2. 常见家务活动 英文 中文 wash dishes 洗碗 water the flowers 浇花 clean the bedroom 打扫卧室 clean the classroom 打扫教室 make the bed 整理床铺 sweep the floor 扫地 take out the trash 倒垃圾 3. 频率小口诀 频率副词句中站，be 后动前记心间。 always 总是 usually 通常，often 经常 sometimes 有时 never 从不。 How often 问频率，once/twice/次数来回答。 need to do 不要丢 to，三单主语动词 s/es 加。 七、单元自测练习 一、用所给词的适当形式填空（每小题2分，共20分） 1.
